Isotopic Composition of the Martian Atmosphere

Science, 1976
Results from the neutral mass spectrometer carried on the aeroshell of Viking 1 show evidence for NO in the upper atmosphere of Mars and indicate that the isotopic composition of carbon and oxygen is similar to that of Earth. Mars is enriched in 15 N relative to Earth by about 75 percent, a consequence of escape ...

Atmospheric Composition and Surface Exchanges

2004
Atmospheric chemistry is a relatively new scientific discipline. Research in this area has intensified dramatically in the last 3–4 decades because of the concerns that growing emissions of pollutants could have severe consequences for humankind. Although the major chemical compounds present in the atmosphere were identified long ago, it is only during

An Introduction to Measurements of Atmospheric Composition

2010
This chapter reviews the basic concepts under the measurements of atmospheric composition. The major challenges are discussed, including the low concentration (usually less than one part per million) of interesting trace gases and the interference among the thousands of species involved in the atmosphere chemistry.
